They should be exactly the same but in my experience the GWS ones are well worth the money. These crack really easily and in some batches you can just throw most of them away because they are so unbalanced.
The perfect prop for the Turnigy L2205-1350 Brushless Motor. Brilliant efficiency, most of them are balanced too and this deserve a 5 star for cheap prop. Oh they are much quieter too then other slow fly prop I've tried.
